I hope it dont go down drastically as it escalated ( beware of bad buyers, that is the Hell pit of Fiverr).

This is why I limited the amount of work I accept from buyers that do first time business with me on Fiverr. I just declined an order of $525,- It’s not because I think that the buyer was a bad guy, but I a had weird experience with a very good buyer once (to complex to tell here) and this was when I decided to limit work I do for people I don’t know or don’t have any experience with.
In my business outside of Fiverr I don’t handle this limits because there I’m also the one who decides about disputes. Luckily I never encounter them.
